I've have learn alot of thing in maths.other I was tought how the to use the australlian currency Exchange Rates. The task was to find 5 item to buy from three other different country. The three country is Canada, USA and England. It has to be the same model. To work out the Exchange Rate i've have to do some working out. By using a method that is very easy to uses, by taking the australlian dollar $50 eg times it with the Canada Currency Exchange Rates 0.94 eg. And you get to know how much $50 worth over Canada. It also work exactly the same as the other countrys. But just use the other country exchange.
